' STIIPLE BRUSH.

Application filed December 19, 1927. Serial No. 241,159. V

This invention relates to stipple brushes.

The primary object of the invention resides in a stipple brush for producing a stipple effect upon a freshly painted surface which includes a brush back having flexible stipple units removably carried thereby.

Another object of the invention is to provide a novel means by which the stipple units are removably mounted on the brush back to facilitate the ready replacement of any unit which may become worn and unfit for use.

A further object of the invention is the provision of a stipple brush including a back or head provided with headed studs, in combination with stipple units, each of which has a distendable opening for the passage of a head therethrough and by which the stippleunits are removably supported upon one face of the head.

With these and other objects in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which Figure 1 is a perspective view of my improved stipple brush.

improvements in Figure 2 is an enlarged detail vertical sectional view through one of the stipple units.

Figure 3 is a similar view showing the relation of the stipple unit before its connection with its respective stud.

Figure 4 is a detail perspective view of one of the stipple units per se.

Referring to the drawings by reference characters, the numeral 10 designates my improved stipple brush in its entirety which includes a back or head 11 having a hand grip 12 on one side thereof with staggered rows of spaced studs 13 extending from the opposite side. Each stud 13 comprises a shank 14 Which enters the head and which has a cone-shaped head 15 on the outer end thereof spaced from the underside of the brush back.

Each stipple unit is designated in its entirety as at 16 and is constructed of soft flexible material such as rubber. A stipple unit is removably aflixed to a stud 13 and comprises a hollow conical body 17 the enlarged end of which is open and the walls slit or bifurcated to providefiexible tongues 18, the free end edges of which constitute stipple surfaces. The reduced end of the body has an opening 19 therein of a diameter less than the diameter of the base of the conical head 15 but larger than the pointed end of the said head. Each stipple unit is removably attached to a respective stud by causing the conical head of the stud to ass through the restricted opening 19, whlch distends the walls of the opening to allow the end of the body to lock beneath plhe Cpead 15 and the underside of the brush This brush is intended for use by painters and decorators for use on freshly painted surfaces to produce a stipple effect, and which is accomplished by gently wiping the flexible tongues 18 against the surface. In brushes of this kind, the paint tends to rot the rubber and unless the brush is thoroughly cleaned after each use of the same, the life of the stipple units is very short. However, by the construction shown, any worn unit may be removed by pulling the same from. its attaching stud and a new one substituted therefor. It is not necessary to remove the studs from the brush back when replacing a stipple unit, as the walls of the opening 19 will distend when a pull is ex erted upon the body of the unit.

While I have described what I deem to be the most desirable embodiment of'my invention, it is obvious that many of the details may be varied without in any way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the whole of my invention limited only by the appended claims.

What is claimed as new is 1. In a stipple brush, a brush back, headed studs extending from one of the faces of said back, and stipple units removably suspended from the respective headed studs, each stipple unit having an opening therein, the walls of which aredistendable over the heads of said studs.

2. In a stipple brush, a brush back, studs extending from 'one of the faces of said brush back, conical heads provided on the extending ends of said studs and being spaced from said brush back, and stipple elements each having an opening therein of a smaller size than said heads, the walls of the openings of the stipple elements being distendable to pass over said heads.

3. In a stipple brush, a stipple unitem brush back, conical heads provided on the outer ends of said studs and being spaced from said brush back, and rubber stipple elements having openings in one end thereof of a size smaller than the diameter of saidheads for receiving the heads of the respective studs.

In testimony whereof I have aflixed my signature. I

AUGUST C. SAKOVICH.
